Subject: Re: [OMPI devel] 1.7.4rc: MPI_F08_INTERFACES_CALLBACKS build failure with PathScale 4.0.12.1

Ah, I see.

Yes, this is what we originally thought was a Pathscale bug, but it later turned out that Pathscale was correct and MPI-3.0 was wrong (which led to a major errata for the mpi_f08 stuff :-( ).

Meaning: Fortran explicitly says that BIND(C) is not compatible with LOGICAL dummy params (which is why we took much BIND(C) usage out in an MPI-3 errata).

Hence, this configure test is not correct; the answer should *always* be "no" (even though most compilers allow it!). Therefore, this litmus test is no good -- we need some another one. Possibilities:

1. Check for BIND(C) name support of > 32 characters
2. Somehow check for the internal compiler errors

#1 is a little tricky because of ABI issues, but is do-able (although I'm not happy about it...).

#2 will truly suck; I don't know what causes the internal error. By definition, it's a compiler bug, and I really don't want to have to test for compiler bugs in a configure test. :-(

It could be that #1 is sufficient. I'm still waiting to hear back from Pathscale.
